Green Tariffs

If you are concerned about your household carbon dioxide
emissions or purchase of nuclear power you might prefer to get your electricity
from renewable energy sources. Many companies offer "green" tariffs.

There are three main types of green electricity supply: green
supply (generated from renewable energy sources), green funds (which use a portion of your
payments to promote renewable energy or other environmental projects) and carbon offset.
Some tariffs provide a combination of more than one of these.
